Most Geographic Information Systems (GIS) have quite
good capabilities with respect to database access and data visualization but
they quite often lack of sophisticated algorithms or informative features relying
on complex computations. One of the main reasons is that most approaches don't
come along with problems due to inexact computations or degenerated problem
instances.
The Software-Büro Lothar Bubel GmbH (SWBB) overcomes
that difficulty by using extensively the geometric part of the L E D
A library
in its products. L E D A on one hand provides data
types and algorithms like polygon intersection, voronoi diagrams and similar
features, on the other hand it performs exact computations with arbitrary
precision.
The figures show several snapshots of SWBB's flagship
application PolyGIS®. It provides for instance an absolutely
error-free module for area intersection and union.
